Despite reaching an epidemic status worldwide, metabolic disorders, notably diabetes, still miss efficient and specific therapeutic strategies because of their multifactorial origin. SHP2 is a ubiquitous tyrosine phosphatase that regulates major signalling pathways (e.g. MAPK, PI3K) in response to many growth factors. The inventors evaluate whether chronic inhibition of SHP2 could improve insulin sensitivity in animal models. Obese diabetic mice were thus treated by gavage (50mg / kg / day). And the inventors note a significant improvement in the glucose tolerance of the treated animals compared to their control, with a decreased fasting blood glucose, without any change in weight or body composition. Accordingly, the present invention relates to use of SHP2 inhibitors for the treatment of insulin resistance.
